WINDOW.

Specification of Letters Patent.

Patented Dec. 18, 1906.

` Appiicaaon ned June 2,1905. serai No. 263.420.

To LZZ whom, it may concern:

Be it known that I, AARON KENT, a citizen of the United States of America, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in IVindows, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in windows, and relates more particularly to a novel form of weather-strip adapted to be used in connection with the sashes thereof.

My improved weather-strip is particularly adapted for use in connection with a Window the sashes thereof being constructed to be swung upon horizontal pivots without interfering with the usual method of raising and lowering said sashes. My improved weatherstrip as applied to the above-described character of window-frame is adapted to render a compartment weather and dust proof when said window is used in connection with said compartment.

The primary obj ect of the invention is to provide a weather-strip which will serve functionally as a lock for securing a windowsash in a vertical or upright position, also serving to close the joints that exist between a pivotally-mounted window-sash and its slide-bars.

Another object of the present invention is to provide a weather-strip which will be positive in its action, simple and inexpensive in its construction, and free from all danger of being broken from ordinary use.

The invention finally consists in the novel construction, combination, and arrangement of parts, to be hereinafter more fully described andthen specifically pointed out in the claim, and, referring to the drawings accompanying this application, like numerals of reference designate corresponding parts throughout the several views, in which- Figure 1 is a front elevation of a windowframe, illustrating a sash and one side of the Fig. 2 is a detail perspective view of the sliding bar of the frame, illustrating the side rails of a sash swung outwardly upon a horizontal plane. Fig. 3 is a vertical sectional view of a portion of a sash and sliding bar, illustrating my improved weather-strip. Fig. 4 is a bottom plan view of a portion of a sash and sliding bar. Fig. 5 is a cross-sectional view of the same, and Fig. 6 is a detail perspective view of my improved weather-strip.

In the accompanying drawings I have illustrated a window-frame 1, having upper and lower sashes 2 and 3 mounted therein. The sashes 2 and 3 are pivotally connected by trunnions 4 to sliding bars 5, which are connected to the ordinary form of weighted sash-ropes 6, that are carried by the frame 1.

My invention resides in providing a novel form of weather-strip adapted to close the joint 7 existing between the side rails of the sashes and the sliding bars 5. The side rails 8 8 of the sashes are provided with verticallydisposed slots or grooves 9, extending from the bottom of said sash to the top thereof. The grooves 9 are preferably located near one edge of the sash, and in the sliding bars slots or grooves 10 are provided which are adapted to mesh or aline with the slots or grooves 9 of the sash. In the slots or grooves 9 of the side rails 8 S I mount my improved weather-strips, which are preferably constructed of a light and durable metal. Each weather-strip consists of a strip of metal 11, having elongated openings 12 formed near its ends, said openings having straight sides and extending diagonally with respect to said strip. Extending into Asaid openings are studs or pins 14 14, carriedby4 the side rails of the sash. The lower end of the strip 11 is bent outwardly, as indicated at 15, and the bottom edge of the sash and sliding bar is cut away, as indicated at 16, to receive the outwardly-bent end 15 of the strip and permit of easy access being had to this end of the strip in order that it may be easily gripped when it is desired to operate the same.

In the present illustration I have shown the weather-strip as having two plies of material that is, a piece of material being used and the edges bent upon themselves, as clearly illustrated in Figs. 5 and 6 of the drawings; but I do not care to confine myself to this construction.

In Fig. 3 of the drawingsI have illustrated the weather-strip in an unlockedv positionthat is, in such a position that the sash carrying the side rail 8 can be readily swung outwardly upon a horizontal plane. In order that the strip may assume this position, the sash is partially raised, said sash having been raised in order that a person may reach IOO IOS

under the lower edge of the sash and pull the weather-strip downwardly to the position illustrated in Fig. 3. When it is desired to close the sash 3 and lock the sash in a vertical position in engagement with its sliding bars, the lower end of the weathenstrip is pushed upwardly, and as the same is mounted upon the studs or pins 14 of the sash and as the elongated openings 12 are diagonally disposed'relative to the strip said strip will travel upwardly into the groove or slot l0 of the sliding bar and will positivelyclose or break the joint existing between the side rails of the sash and its sliding supportingbars. As the guides or parting-strips protect the joint formed between the sliding bars and the window-frame, the compartmentin connection with which the window is used will be weatherproof and dustproof and an almost air-tight connection established between the different movable parts of the window. I do not care to limit myself to the form of pivotal connection used between the window-sashes and their sliding bars or to themeans employed for elevating said sashes,

It is thought from the foregoing that the construction, operation, and advantages of the herein-described window will be apparent without further description, and various changes maybe resorted to in the form, proportion, and minor details of construction without departing from the spirit of the invention or sacriiicing any of the advantages thereof.

I/Vhat I claim, and desire to secure by Letters Patent, isi l The combination with a window-frame of grooved sliding bars, a window-sash having grooves on its edges registering with the grooves in the sliding bars, said window-sash being pivotally attached to said sliding bars and metallic strips having diagonal slots,'said strips being each composed of a piece of material doubled on itself, said strips being arranged in grooves in the window-sash and said sash being provided with pins passing through the slots in the strips, the windowsash and sliding bars being cut away at the lower ends of said grooves and the ends of the strips being bent outwardly and resting in the cut-away portions of the bars and the window-sash, said strips when moved downwardly projecting below the lower edge of the sash, and when in this position resting entirely within the grooves in the sash, and said strips being adapted when the sash is lowered to contact with the frame and to be Jforced into the grooves in the sliding bars.

In testimony whereof I aliX my signature in the presence of two witnesses.

AARoN KENT.
